Theory chaos

A mathematician would classify the SCF equations as nonlinear equations. The term nonlinear has different meanings in different branches of mathematics. The branch of mathematics called chaos theory is the study of equations and systems of equations of this type. [Pg.193]

The values could be almost repeating but not quite so. In chaos theory, these are called Lorenz attractor systems. [Pg.193]

Changing the constants in the SCF equations can be done by using a dilferent basis set. Since a particular basis set is often chosen for a desired accuracy and speed, this is not generally the most practical solution to a convergence problem. Plots of results vs. constant values are the bifurcation diagrams that are found in many explanations of chaos theory. [Pg.194]

Rt is ironic that such an intensely computational mathematical science as chaos theory owes much of its modern origin to calculations that were performed not on a large mainframe computer but rather a simple programmable pocket calculator, a Hewlett-Packard HP-65 Feigenbaum would explain years later that had the series of intermediate calculations not been carried out sufficiently slowly, it is likely that most of the key observations would have been missed [feigSOa]. [Pg.177]

As far as an external aesthetic is concerned, we do have two important clues to help guide us (1) chaos theory, from which we learn that natural processes that appear complicated can often be well understood using relatively simple rules, and (2) complex systems theory, from which wc learn that interesting phenomena often emerge on higher levels from parts that are mutually interacting on the lower levels of a hierarchy. [Pg.700]

Lahey (1990) indicated the applications of fractal and chaos theory in the field of two-phase flow and heat transfer, especially during density wave oscillations in boiling flow. [Pg.508]

Despite the nature of the environmental regulations and the precautions taken by the refining industry, the accidental release of nonhazardous chemicals and hazardous chemicals into the enviromnent has occurred and, without being unduly pessimistic, will continue to occur (by aU industries—not wishing to select the refining industry as the only industry that suffers accidental release of chemicals into the environment). To paraphrase chaos theory, no matter how well one prepares, the unexpected is always inevitable. [Pg.151]

Of course, none of us could have known that much of the mathematical research of the decades ahead would explore just such ideas under the name of chaos theory and dynamics.]... [Pg.67]

A mathematically definable structure which exhibits the property of always appearing to have the same morphology, even when the observer endlessly enlarges portions of it. In general, fractals have three features heterogeneity, setf-similarity, and the absence of a well-defined scale of length. Fractals have become important concepts in modern nonlinear dynamics. See Chaos Theory... [Pg.297]

Decades after Ramanuj an, many of the modem world s greatest minds have been inspired by marijuana and psychedelics. As just one example, Ralph Abraham, a pioneer in chaos theory and Professor of Mathematics at the University of California, explained how psychedelic insights influence mathematical theories ... [Pg.348]

ZEEMAN, ERIK CHRISTOPHER (1925-). Zeeman was an English mathematician. His doctoral work was in pure mathematics and he received his Ph D. in 1954 for a thesis on knots and all the algebra you need to actually prove the existence of knots. He did research in topology, which is a type of geometry that examines the properties of shapes in many dimensions. His best known work was in catastrophe theory. His work has consequences for a broad range of fields from weather to psychiatry. Zeeman also made contributions in the development of the chaos theory. [Pg.1773]

Although best known as an astronomer, Brahe was also a follower of Paracelsus, and a number of medicines that he concocted found their way into the official Danish pharmacopoeia. For years Tycho also kept a detailed weather diary, convinced that weather patterns held vital secrets. It was not until 1960 that Tycho s hunch was proved right — Edward Lorenz s studies of weather patterns led to the invention of a new science chaos theory. [Pg.126]
